The University of Texas at Austin and the National Park Service provide maps of the national parks in Texas. Aside from maps, both sites offer state park guides, transportation options and directions to the parks.
The official website of the NPS provides a Web map showing the location of all the listed national parks in the state. To access the map, navigate to the NPS homepage, and choose Texas under the Find a Park search box drop-down menu. The interactive map has a zoom feature for easier viewing of U.S. and interstate highways and the general direction of the park. To view a more detailed map of the park, click a park's name under the Texas Parks list under the map, and click Plan Your Visit on the next page. Under Directions & Transportation, click Maps to access an area, backcountry zone or topographic map of the park.
The Perry-Castañeda Library Map Collection at the University of Texas at Austin provides a list of national, state and wildlife refuge parks in the state. Most of the maps are outdated, but they still provide useful information for online users who want a PDF copy of all listed parks in Texas. For updated information, visit the Texas Parks and Wildlife Department's website to get the Texas State Park Guide, which also includes information about Texas national parks. The TPWD site sends copies of the guide for free upon request.
